character to the feet of an ordinary typewriter, the screws or fasteningdevlces are removed and the old plugs or pads discarded. The new plugsare now brought into position, and the screws passed upward through theholes 7 into the feet or threaded sockets therein, so that the upperplugs are'held against said feet with theii shanks downward; Now thespiral springs are screwed onto these shanks, their uppermost coils orconvolutions15 slightly embed- 'ding the rubber of the shank so that thesprings will not fall off. Finally the lower plugs are screwed into thelower ends of the springs, with the same result. The typewriter is nowset onto the table or desk and its weight compresses the'devices so thatit is eventually distributed to the four'springs Now when theoperatorflwritea her blows 'writingis deadened as firstvab ovesuggested.
